I am trying to add an XCUITest target to an existing application. When I try to run the tests, I get the error "Invalid configuration: MyProjectUITests sets both USES_XCTRUNNER and either TEST_HOST or RUNTIME_TEST_HOST".

I have seen information stating that it might be because I have multiple apps built from different build configurations in the same scheme, but I could not resolve the issue with any of the suggestions I saw.

I've attached a screenshot of the error message and a link to a project stripped down to just the existing configuration to help with diagnosing this issue. I would really love to be able to get some UI tests running.

I get the error "Invalid configuration: MyProjectUITests sets both USES_XCTRUNNER and either TEST_HOST or RUNTIME_TEST_HOST".

The above error indicates you override the value of Test Host in the Build Settings pane of your Xcode project. You should set this build setting for unit tests. Clear its value for your UI test target.

Select your UI test target in the project navigator, click its Build Settings pane, then search for Test Host. Scroll to this setting, then clear its value for both Debug and Configuration configurations.
